picture info	Ligature (medicine) In surgery or medical procedure, a ligature consists of a piece of thread ( suture) tied around an anatomical structure, usually a blood vessel or another hollow structure (e.g. urethra) to shut it off. History The principle of ligation is attributed to Hippocrates and Galen. In ancient Rome, ligatures were used to treat hemorrhoids. The concept of a ligature was reintroduced some 1,500 years later by Ambroise Paré, and finally it found its modern use in 1870–80, made popular by Jules-Émile Péan. Procedure With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat. It is different from a tourniquet in that the tourniquet will not be secured by knots and it can therefore be released/tightened at will. Ligature is one of the remedies to treat skin tag, or acrochorda. It is done by tying str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Ligature (orthodontic) Elastics are rubber bands frequently used in the field of orthodontics to correct different types of malocclusions. The elastic wear is prescribed by an orthodontist or a dentist in an orthodontic treatment. The longevity of the elastic wear may vary from two weeks to several months. The elastic wear can be worn from 12 to 23 hours a day, either during the night or throughout the day depending on the requirements for each malocclusion. The many different types of elastics may produce different forces on teeth. Therefore, using elastics with specific forces is critical in achieving a good orthodontic occlusion. The term ''intermaxillary elastics'' is used when elastics can go from the maxillary to the mandibular arch. ''Intra-maxillary elastics'' are elastics used in one arch only, either mandibular or maxillary. People using elastics for orthodontic correction change their elastics three to four times during the day. Elastic wear is recommend to be used in a rectangular wire to min ...

picture info	Ligature (music) In music notation, a ligature is a graphic symbol that tells a musician to perform two or more notes in a single gesture, and on a single syllable. It was primarily used from around 800 to 1650 AD. Ligatures are characteristic of neumatic (chant) and mensural notation. The notation and meaning of ligatures has changed significantly throughout Western music history, and their precise interpretation is a continuing subject of debate among musicologists. History Plainchant The early notation of plainchant, particularly Gregorian chant, used a series of shapes called neumes, which served as reminders of music that was taught by rote rather than as an exact record of which notes to sing. Neumes were in use from the 9th through the 11th centuries AD for most plainsong, and differed by region. Due to their malleable nature, there were no hard and fast rules for the lengths each note was supposed to last, or even how high or low the intervals between notes were to be. ''De mensurabili ...

picture info	Ligature (instrument) A ligature is a device which holds a reed onto the mouthpiece of a single-reed instrument such as a saxophone or clarinet. The ligature must secure the reed firmly against the table of the mouthpiece while allowing it to vibrate freely. The earliest ligatures were lengths of string wrapped over the reed and tied. Iwan Müller invented a metal ligature to replace twine. String is still used by clarinetists, especially in Germany. Modern German mouthpieces have a groove cut into the outside of the mouthpiece to facilitate wrapping with a string ligature. Some modern clarinetists even opt to use shoestring as a ligature substitute as it is more easily adjustable than string. Other modern clarinetists use electrical tape as a ligature. A ligature must be placed properly in order to allow best performance on a reed instrument. The ligature must be placed at least halfway down the stock of the reed and the screws must not be overtightened, in order to allow free vibration and not disto ...

picture info	Ligature (writing) In writing and typography, a ligature occurs where two or more graphemes or letters are joined to form a single glyph. Examples are the characters æ and œ used in English and French, in which the letters 'a' and 'e' are joined for the first ligature and the letters 'o' and 'e' are joined for the second ligature. For stylistic and legibility reasons, 'f' and 'i' are often merged to create 'ﬁ' (where the tittle on the 'i' merges with the hood of the 'f'); the same is true of 's' and 't' to create 'ﬆ'. The common ampersand (&) developed from a ligature in which the handwritten Latin letters 'E' and 't' (spelling , Latin for 'and') were combined. History The earliest known script Sumerian cuneiform and Egyptian hieratic both include many cases of character combinations that gradually evolve from ligatures into separately recognizable characters. Other notable ligatures, such as the Brahmic abugidas and the Germanic bind rune, figure prominently throughout ancient manuscript ...
